We theoretically investigate the possibility of generating pulses in an excitable (asymmetric)
semiconductor ring laser (SRL) using optical trigger pulses. We show that the phase …

It was demonstrated that the chaos-driven FitzHugh–Nagumo (FHN) neuron can be
considered as a logic system to implement the reliable logical operations through the …

Considering time delays in the deterministic and stochastic forces, we construct stochastic
delayed differential equations to investigate the regime shifts in an insect ecosystem. The …

A model of tumor–immune system interplay with time delays and cross-correlated sine-
Wiener noises is investigated by numerical simulations for the stationary probability …

We report on the experimental observation of coherence resonance in a bistable system
with delay. Our system consists of a vertical-cavity surface-emitting laser subject to time …

Immunotherapy is one of the most recent approaches in cancer therapy. A mathematical
model of tumor–immune interaction, subject to a periodic immunotherapy treatment (imitated …

Feedback connections and noise are ubiquitous features of neuronal networks and affect in
a determinant way the patterns of neural activity. Here we study how the subthreshold …

Inspired by the recent observation of memory effects in the nonlinear optical response of a
coherently-driven micro-cavity, we investigate the effects of varying the memory time on the …

We study theoretically a bistable system with time-delayed feedback driven by a weak
periodic force. The effective potential function and the steady-state probability density are …

In this paper, the regime shift behaviors between the prosperous state and the extinction
state and stochastic resonance (SR) phenomenon for a metapopulation system subjected to …
